Replacement Parts for an EA21R

[Chris da Silva]

Can anyone clarify two problems for me, please? Here they are:

1. Is the exhaust manifold for a K6A engine 14111-73G03, or is it 14111-54A50? I'm asking because the mechanic servicing the car has put down the latter as the replacement for the one still bolted on the engine! As far as I know, the latter belongs to the EA11R's engine while the former is assigned to the EA21R. So have the two numbers merged? (The latter number, BTW, is no longer available.) Alternatively, is there a new number assigned to the exhaust manifold?

2. I also tried ordering up a replacement timing chain tensioner using the part number 12831-73G00; but it's no longer available from the factory! Has this part also been given a new part number that I don't know of?

Thanks if anyone can help.

You are quite right about all the part nos. It is possible that the differences between the manifolds is minor, so either will do, but perhaps not, because, in such cases, it is usually only the last two digits which differ.

The K6A engine is widely used on snowmobiles and the like, so it's possible that a new tensioner is used and will fit, but we have no way of knowing. Dealers may have access to updated parts lists, but not usually for cars not exported e.g. the Type 3 Cappo.
